FACTS ABOUT PNW ELECTRIC REVEALED

Consider the Specific case of a beneficial stage charge q for the origin. To estimate the prospective due to q in a length r through the origin relative into a reference of 0 at infinity (remember that we did the same for possible Vitality), Allow (P = r) and (R = infty), with (dvec l = dvec r = hat r dr) and use (vec E = frac kq r^two hat r ).
